Result

The color palette generator creates a small set of related colors from a single base color.

It is meant for interface work, brand drafts, quick prototypes, CSS themes, and visual experiments that need a coherent starting point.

The generated palette is shown as swatches and as CSS custom properties, so the same values can move straight into a stylesheet.

All calculations happen locally with standard color math, and clicking a swatch copies its HEX value for fast reuse.
